1 Unable to locate the Javac Compiler in: 2 C:\Program Files\Java\jre1.6.0_07\..\lib\tools.jar 3 Please ensure you are using JDK 1.4 or above and 4 not a JRE (the com.sun.tools.javac.Main class is required). 5 In most cases you can change the location of your Java 6 installation by setting the JAVA_HOME environment variable.

将jre设置为jdk即可
